<h1>RMF --- Raster Matrix Format</h1>

RMF is a simple tiled raster format used in the GIS "Integration" and
"Panorama" GIS. The format itself has very poor capabilities.<p>

There are two flavours of RMF called MTW and RSW. MTW supports 16-bit integer
and 32/64-bit floating point data in a single channel and aimed to store DEM
data. RSW is a general purpose raster. It supports single channel colormapped
or three channel RGB images. Only 8-bit data can be stored in RSW. Simple
georeferencing can be provided for both image types.<p>

<h2>Metadata</h2>
<ul>
	<li> <b>ELEVATION_MINIMUM</b>: Minimum elevation value (MTW only).<p>

	<li> <b>ELEVATION_MAXIMUM</b>: Maximum elevation value (MTW only).<p>

	<li> <b>ELEVATION_UNITS</b>: Name of the units for raster values
	(MTW only). Can be "m" (meters), "cm" (centimeters),
	"dm" (decimeters), "mm" (millimeters).<p>

	<li> <b>ELEVATION_TYPE</b>: Could be either 0 (absolute elevation)
	or 1 (total elevation). MTW only.<p>

</ul>

<h2>Creation Options</h2>
<ul>
	<li> <b>MTW=ON</b>: Force the generation of MTW matrix (RSW will be
	created by default).<p>

	<li> <b>BLOCKXSIZE=n</b>: Sets tile width, defaults to 256.<p>

	<li> <b>BLOCKYSIZE=n</b>: Set tile height.  Tile height defaults to 256.<p>

        <li> <b>RMFHUGE=NO/YES/IF_SAFER</b>: Creation of huge RMF file (Supported by GIS Panorama since v11). Defaults to NO.<p>

</ul>
